Firefox 社群討論區

I've been searching for an answer to this for weeks to no avail. It concerns YouTube videos "autoplay"ing on YouTube. Many have asked this question and most responses state to shut off Autoplay. These are two separate issues. AotuPlay means the next video on YouTube will advnace automatically requiring no user input. If Autoplay is off, streaming stops at the end of the video. The issue I am having is when I open a YouTube video to a new tab (but do not switch to that tab), the video WILL start playing as soon as that tab is in focus. This never used to happen and indeed, on two other computers with the settings and extensions all sync'ed, this doesn't happen, except for on this one computer. Today I found someone that posted the exact same problem 5 years ago and didn't get an answer. He seems to describe it well:

1. Okay, so before, when I loaded up 100+ Youtube videos, they stayed when switching tabs - no autoplay. Suddenly they decide to autoplay when switching tabs - note, I've not done anything to my settings or plugins. Fair enough, maybe you changed something (which you often do, without informing). So I check the options. It was on "Block audio", which obviously didn't work, so I tried "Block Audio and Video" - which WORKS, but now both the video is paused (which I want) AND the audio is set to mute (which I DON'T want) - so... what does it take to have Youtube wait for a click to start playing a video loaded in a background tab, but KEEP AUDIO ACTIVE, so I don't also have to unmute the damn video?

One person posted a possible solution: Maybe check this pref on the about:config page.

   media.block-autoplay-until-in-foreground 

This setting describes the issue kind of. If you have this set to false, the moment you send a link to a new tab, YouTube starts playing in the background. Setting it to false keeps the video paused until that tab is in focus. That is how mine has always been set. What I am looking for is a setting that would say something like: "block autoplay until play is pressed"

Thanks in advance and sorry for being so long-winded

Hi,

I installed Debian 12 on my laptop. I'm using Firefox 133.0.3 from Flatpak. When the browser is in full screen and I display a video in full screen mode, strangely, the video is not in full screen... It's on the top left corner and the rest of the page is in violet. I tested on different site, loading a local video and the issue is the same. I can't reproduce the issue on my desktop computer on Windows. When the browser is not in full screen (F11) and I put the video in full screen mode, there is no issue... I attached a screenshot of the situation.

Have you ever encountered this kind of issue? How to resolve it?

Thanks

Firefox will not play video from a website. If I save the video, it is a MP4 file. Windows Media Player and VLC will play the video file. But the browser shows the message: "No video with supported format and MIME type found."

Chrome and Edge will play this video correctly in their browsers. Firefox will not play the video on 3 different computers, and even when a different user account is involved (without Firefox sync).

The evidence seems to point at firefox. The website is a Wordpress site.

Is it possible that the website is the problem? If so, why do Edge and Chrome work?

I uninstalled Firefox (latest version) and reinstalled it. Not fixed.

My windows updates are current, as are Dell updates.

This is stumping me. I hope someone can help.

So, my problem is with HW acceleration in FF. Basically:

If its enabled: It causes graphical artifacts in videos [See screenshot]. If its disabled: It brings screen tear in to videos and autoscroll [Like if Vsync is disabled in games].

I tried safe mode, I tried reinstall of FF, I tried disabling and enabling extensions. I tried to set Vsync on in Nvidia control panel... the only thing that impact those bugs is HW acceleration in FF.

My drivers are up to date, my browser is up to date, yet there is such trouble.

Any ideas or solutions?

I have installed a analog to digital converter software to convert High8 tapes to digital. It is all hooked up, but the video and audio from the converter program will no show on computer. Help!

I have Win 11 dell computer that does not play or pick up sound from web sites videos .I checked and tested my sound using the Microsoft platform & buy playing a disc. It works OK

Following a recent update of my bios (AMD Ryzen) of my PC the on-board sound system failed. I chased down the issue, got a sound card to circumvent the on-board circuits, and had sound once again but for my FireFox (Ver 133.0.3, on Windows 11 Home, Ver 10.0.22631 Build 22631). Testing with alternate browsers (Edge, Opera) the sound works, as do my downloaded games and music but no joy with FireFox.

My question: Is this a known issue being addressed for a future update or are my circumstances an outlier issue?

For many years, I have been exchanging video calls on Facebook.

Recent attempts to video call the same person I've been video calling for the past 3 years result in "your browser doesn't support video calls"

Have I been "hacked"?

Please explain.

Could a real person answer this question for me, please? Thank you.

There used to be dozens of video downloaders. Now, none of them work except for one that requires a ridiculous fee. Are there still youtube video downloaders that still work

Youtube brought up in the broswer works fine with audio/video but on other websites I can view the video and can't hear the audio.

My account on thinkific is cookingasmedicine.thinkific.com When I go to the "course" and click on a video whether in my class or one I am taking, the videos will NOT play. I have been talking with Thinkific and we've gone through all the videos of yours and theirs - the settings, checked my updates and nothing works. I have no trouble on my laptop or my Iphone using firefox on laptop just on my desktop LENOVO.

I checked my set up that is on the laptop and made it exactly the same on my desktop but STILL to no avail. The videos will simply NOT play!

Would you please help me?

I have Windows 10 and currently have auto updates so I am up to date with your updates. I just can't imagine what it could be that's stopping the videos from playing? They played perfectly for three years! I have not put any new apps or programs on my computer either.

Thank you, Claire

Hello,

I am a new firefox user and would like to use it 100%, but have been running into a few bugs. This one I have been unable to find this issue myself, so thought I would ask here. I use Qobuz to stream hi-res music up to 24bit/ 192kHz. Some albums do not have sound at that resolution. The file will load and timer shows the song is playing, but there is no audio. I can change the setting to stream at 16bit/44.1kHz and then I get audio. Again, this does not occur with all albums, some will stream at hi-res and some will not. An interesting note: the same file with no audio at hi-res on firefox will have audio at same resolution setting on chrome. The only thing I can think of is chrome is reducing resolution in the background, or maybe a DRM issue? I do have "Play DRM-controlled content" checked in firefox settings.

p.s. I am aware that streaming music through a browser is not necessarily the best way to listen to hi-res music, and my ears may, or may not hear the difference between the 16bit and 24bit. However, the issue is the functionality, or lack of.

Thank you in advance for any insight.

After a Windows 11 update, every time I play some video/sound and stop the playback, my whole computer audio doesn't work anymore. When I reset my computer, the audio comes back again. I tried using other browsers (Edge, Chrome, etc.) and other programs/applications, but this only happens in Firefox.

Any ideas on what can I do to solve this issue?
